Obesity remains a serious health problem and it is no secret that many people want to lose weight. Behavioral economists typically argue that “nudges” help individuals with various decisionmaking flaws to live longer, healthier, and better lives. In an article in the new issue of Regulation, Michael L. Marlow discusses how nudging by government differs from nudging by markets, and explains why market nudging is the more promising avenue for helping citizens to lose weight.

Two long wars, chronic deficits, the financial crisis, the costly drug war, the growth of executive power under Presidents Bush and Obama, and the revelations about NSA abuses, have given rise to a growing libertarian movement in our country – with a greater focus on individual liberty and less government power. David Boaz’s newly released The Libertarian Mind is a comprehensive guide to the history, philosophy, and growth of the libertarian movement, with incisive analyses of today’s most pressing issues and policies.

That’s why I’m particularly interested in some new research by Cornell University’s Karel Mertens.

Here are some key findings from Mertens’ study, beginning with some observations on existing research.

To what extent do marginal tax rates matter for individual decisions to work and invest? The answer is essential for public policy and its role in shaping economic growth. The strand of the empirical literature that uses tax return data, surveyed in Saez, Slemrod and Giertz (2012), finds that incomes before taxes react only modestly to marginal tax rates and that the response is mostly situated at the very top of the income distribution.

So what does this mean? A lot depends on how one defines “modestly,” though it’s worth noting that even very small changes in growth—if sustained over time—can have big impacts on prosperity. That, in turn, has a significant effect on government finances.

And I have no objection to the assertion that upper-income taxpayers are most sensitive to changes in tax rates. After all, people like me who rely on wage and salary income don’t have much opportunity to alter our compensation in response to changes in tax rates.

I’m not reluctant to criticize my friends at the Heritage Foundation. In some cases, it is good-natured ribbing because of the Cato-Heritage softball rivalry, but there are also real policy disagreements.

That being said, I’m also willing to defend Heritage if the organization is being wrongly attacked. The specific issue we’ll review today is “austerity” in Europe and whether Senator Sheldon Whitehouse of Rhode Island is right to accuse Heritage of “meretricious” testimony.

Let’s look at the details.

Earlier this month, Paul Krugman wrote that, “a Heritage Foundation economist has been accused of presenting false, deliberately misleading data and analysis to the Senate Budget Committee.” Krugman was too clever to assert that the Heritage economist “did present” dishonest data, but if you read his short post, he clearly wants readers to believe that an unambiguous falsehood has been exposed.

Conn Carroll of the Washington Examiner explains that the Heritage economist was looking at OECD data for 2007-2012 while critics are relying on an OECD survey of what politicians in various countries say they’ve done since 2009 as well as what they plan to do between now and 2015.

Whitehouse believed he had caught Furth and The Heritage Foundation in a bald face lie. …There is just one problem with Whitehouse’s big gotcha moment: The staffer who spoon-fed Whitehouse his OECD numbers on “the actual balance between spending cuts and tax increases” failed to also show Whitehouse the front page of the OECD report from which those numbers came. That report is titled: “Fiscal consolidation targets, plans and measures in OECD countries.” Turns out, the numbers Whitehouse used to attack Furth for misreporting “what took place in Europe” were actually mostly projections of what governments said they were planning to do in the future (the report was written in December 2011 and looked at data from 2009 and projections through 2015). At no point in Furth’s testimony did he ever claim to be reporting about what governments were going to do in the future. He very plainly said his analysis was of actual spending and taxing data “to date.” Odds are that Whitehouse made an honest mistake. Senators can’t be expected actually to read the title page of every report from which they quote. But, considering he was the one who was very clearly in error, and not Furth, he owes Furth, and The Heritage Foundation an apology. Krugman and Matthews would be well advised to revisit the facts as well.

In other words, critics of Heritage are relying largely on speculative data about what politicians might (or might not) do in the future to imply that the Heritage economist was wrong in his presentation of what’s actually happened over the past six years.

So far, we’ve simply addressed whether Heritage was unfairly attacked. The answer, quite clearly, is yes. If you don’t believe me, peruse the OECD data or peruse the IMF data.

Now let’s briefly touch on the underlying policy debate. Keynesians such as Krugman assert that there have been too many spending cuts in Europe. The “austerity” crowd, by contrast, argues that strong steps are needed to deal with deficits and debt, though they are agnostic about whether to rely on spending reforms or tax increases.

In the grand scheme of things, however, I think Europe is still headed down the wrong path. Here’s what I wrote back in January and it’s still true today.

I don’t sense any commitment to smaller government. I fear governments will let the spending genie out of the bottle at the first opportunity. And we’re talking about a scary genie, not Barbara Eden. And to make matters worse, Europe faces a demographic nightmare. These charts, reproduced from a Bank for International Settlements study, show that even the supposedly responsible nations in Europe face a tsunami of spending and debt over the next 25-plus years. So you can understand why I don’t express a lot of optimism about European economic policy.

By the way, I’m not optimistic about the long-term fiscal outlook for the United States either. In the absence of genuine entitlement reform, we’ll sooner or later have our own fiscal crisis.

What makes this cartoon so effective is that it properly and cleverly identifies what’s really driving the political class on this issue. They want more revenue to finance a bigger burden of government spending.

Now the bureaucrats have concocted another scheme to increase the size and scape of government. The OECD just published a study on “Addressing Base Erosion and Profit Shifting” that seemingly is designed to lay the groundwork for a radical rewrite of business taxation.

…the BEPS report…calls for dramatic changes in corporate tax policy based on the presumption that governments are not seizing enough revenue from multinational companies. The OECD essentially argues that it is illegitimate for businesses to shift economic activity to jurisdictions that have more favorable tax laws. …The core accusation in the OECD report is that firms systematically—but legally—reduce their tax burdens by taking advantage of differences in national tax policies.

Ironically, the OECD admits in the report that revenues have been trending upwards.

…the report acknowledges that “… revenues from corporate income taxes as a share of gross domestic product have increased over time. …Other than offering anecdotes, the OECD provides no evidence that a revenue problem exists. In this sense, the BEPS report is very similar to the OECD’s 1998 “Harmful Tax Competition” report, which asserted that so-called tax havens were causing damage but did not offer any hard evidence of any actual damage.

To elaborate, the BEPS scheme should be considered Part II of the OECD’s anti-tax competition project. Part I was the attack on so-called tax havens, which began back in the mid- to late-1990s.

Yes, some parts of the budget are disproportionately impacted, such as defense. But even the defense budget climbs over the 10-year period and the United States will still account for close to 50 percent of global military outlays when the dust settles.

But the new President of France, Francois Hollande, doesn’t seem overly concerned by economic rationality and decided (Obama must be quite envious) that a top tax rate of 75 percent is fair. And patriotic as well!

French Prime Minister: “I’m upset that the wildebeest aren’t remaining still for their disembowelment.”

But he’s not the only one. The nation’s top actor also decided that he doesn’t want to be a fatted calf. Indeed, it appears that there are entire communities of French tax exiles living just across the border in Belgium.

Best of all, the greedy politicians are throwing temper tantrums that the geese have found a better place for their golden eggs.

France’s prime minister has slammed wealthy citizens fleeing the country’s punitive tax on high incomes as greedy profiteers seeking to “become even richer”. Jean-Marc Ayrault’s outburst came after France’s best-known actor, Gerard Dépardieu, took up legal residence in a small village just over the border in Belgium, alongside hundreds of other wealthy French nationals seeking lower taxes. “Those who are seeking exile abroad are not those who are scared of becoming poor,” the prime minister declared after unveiling sweeping anti-poverty measures to help those hit by the economic crisis. These individuals are leaving “because they want to get even richer,” he said. “We cannot fight poverty if those with the most, and sometimes with a lot, do not show solidarity and a bit of generosity,” he added.

In the interests of accuracy, let’s re-write Monsieur Ayrault’s final quote from the excerpt. What he’s really saying is: “We cannot buy votes and create dependency if those that produce, and sometimes produce a lot, do not act like morons and let us rape and pillage without consequence.”

So as France gets ever-closer to fiscal collapse, part of me gets a bit of perverse pleasure from the news. Not because of dislike for the French. The people actually are very nice, in my experience, and France is a very pleasant place to visit. And it was even listed as the best place in the world to live, according to one ranking.

But it helps to have bad examples. And just as I’ve used Greece to help educate American lawmakers about the dangers of statism, I’ll also use France as an example of what not to do.

Hopefully we’re all disgusted when insiders rig the system to rip off taxpayers. And I suspect you’re not surprised to see that the worst example on that list comes from California, which is in a race with Illinois to see which state can become the Greece of America.

The numbers are even larger in California, where a state psychiatrist was paid $822,000, a highway patrol officer collected $484,000 in pay and pension benefits and 17 employees got checks of more than $200,000 for unused vacation and leave. The best-paid staff in other states earned far less for the same work, according to the data.

Wow, $822,000 for a state psychiatrist. Not bad for government work. So what is Governor Jerry Brown doing to fix the mess? As you might expect, he’s part of the problem.

…the state’s highest-paid employees make far more than comparable workers elsewhere in almost all job and wage categories, from public safety to health care, base pay to overtime. …California has set a pattern of lax management, inefficient operations and out-of-control costs. …In California, Governor Jerry Brown hasn’t curbed overtime expenses that lead the 12 largest states or limited payments for accumulated vacation time that allowed one employee to collect $609,000 at retirement in 2011. …Last year, Brown waived a cap on accrued leave for prison guards while granting them additional paid days off. California’s liability for the unused leave of its state workers has more than doubled in eight years, to $3.9 billion in 2011, from $1.4 billion in 2003, according to the state’s annual financial reports. …The per-worker costs of delivering services in California vastly exceed those even in New York, New Jersey, Illinois and Ohio.

I suppose the silver lining to that dark cloud is that many bureaucrats now rank as part of the top 1 percent, so they’ll have to recycle some of their loot back to the political vultures in Sacramento.

But the biggest impact of the tax hike—as shown in the Ramirez cartoon—will be to accelerate the shift of entrepreneurs, investors, and small business owners to states that don’t steal as much. Indeed, a study from the Manhattan Institute looks at the exodus to lower-tax states.

The data also reveal the motives that drive individuals and businesses to leave California. One of these, of course, is work. …Taxation also appears to be a factor, especially as it contributes to the business climate and, in turn, jobs. Most of the destination states favored by Californians have lower taxes. States that have gained the most at California’s expense are rated as having better business climates. The data suggest that many cost drivers—taxes, regulations, the high price of housing and commercial real estate, costly electricity, union power, and high labor costs—are prompting businesses to locate outside California, thus helping to drive the exodus.
